PATENT CHARLES RICHARDSON, OF AUBURN, NE\V YORK.

Specification forming part of Letters Patent No. 33,452, dated October 8, 1861.

To all whom it may concern.-

Be it known that I, CHARLES RICHARDSON, of Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Rolls for Rolling and Oreasing Iron for Horseshoes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, in which Figure 1 represents an elevation of said rolls as mounted in housings and ready for operation. Fig. 2 represents the rolls on an enlarged scale. Figs. 3 and at represent crosssections through the upper roll. Figs. 5 and 6 represent cross-sections through the iron in its different stages of perfection after being passed through the rolls.

In making horseshoes it has been found to be very essential to give to the inside of the shoe a convex shape, so that mud or other adhesive soil may not adhere to it easily. This shape of the horseshoe will not only prevent What is called the balling of the foot with snow or mud, but greatly facilitates the labor of the animal when it has to walk over stiff clay, as it requires less power to withdraw a horseshoe of the said description from stiff clay than one with a fiat sole and vertical sides.

My invention therefore relates to the peculiar construction of th e rolls by means of which the iron for making horseshoes is rolled into such a shape that when bent in the form of a horseshoe the inner side of the same shall be convex, said rolls being also provided with suitable creasers for creasing the iron and with pointers or guides for making the length of each blank and defining where the creasing is to be done.

It also relates to the application to said rollers of removable creasers and pointers by which I am enabled to use steel creasers and pointers on cast-iron rolls, and also to renew or repair them when they are Worn out.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A represents a frame or housing in which the rolls B and C are mounted in the usual manner. The creasers a are set in proper recesses of the rolls B, and are retained therein from moving radially by the pins b, as represented in Fig. 3, which pass through them. They are also prevented from moving'longitudinally by the collar D, which is set on the journal E of the roll B. This collar is secured to the roll by means of the screws 0.

h represents pointers for gaging and marking the length of the blanks. They are set in suitable recesses of the collar D, as represented in Fig. 4, and theyare prevented from moving radially by the screws 0, which pass through them. i

The shape of the groove G of the rolls C is represented in the drawings, from which it will be seen that the part 1 of said groove is concave to form the convex side of the iron which is to be theinner side of thehorseshoe. The part 2 is flat for the sole of the shoe, and the part 3 is slightly concave. This latter side is intended for the outside of the shoe and is made such that it will be flat, or nearly so, after the shoe has been creased by the displacement of the material by the creasers, as will be more fully hereinafter described. The fillet I forms two faces on the upper side of the iron, one slightly inclined in relation to the other. The horizontal face 5 is on the outer edge of the shoe, and it only is intended to come in contact with and to be secured to the outer crust or shell of the hoof, While the inner part 4 is sufficiently inclined as to clear the inner and softer part of said boot. The shape of the iron, after being passed through the groove G, is such as represented in Fig. 5 on an enlarged scale. To complete the blank it is passed through the groove H To accomplish this its position is inverted, as represented in Fig. (i, and passed between the roll 0 and the collar D, the concave part of Which corresponds with the convex part 1, and the creasers now out the creases into the iron and displace the metal sufficiently so as almostto fill the corner between the creasers and the neck m of the rolls. From this it will be seen that if sufficient allowance were not made for the displacement of the metal by the creasers the machine could not be worked properly, as the metal would be crowded between the rolls and either arrest their motion or break parts of the machine. The pointers h as the rolls revolve mark off the length of the blanks, which are then cut oif from the bar and bent to the shape of horseshoes.

The ereasers a may have square projections S0 shaping the grooves in the rolls as to roll n on their outer edges for the purpose of markout a bar of the form in er ss-secti n as that ing or punehing the holes whih are to be shown in Fig. 5 and filling out the slack cormadein the hors'eshoes. The manner of makner between the points 2 3 by the after creasing these as Well as the pointers removable ing of said bar, for the purpose and in the permits them to be easily repaired or renewed, manner set forth. and admits the use of steel creasers and pointers 0n cast-iron rolls.
